Does Coca-Cola made with cane sugar — aka Mexican Coke — really taste better than the U.S. version made with high-fructose corn syrup, as President Donald Trump claims? Not quite, according to some studies.

Asked about the switch, a representative for Coca-Cola didn’ explicitly say it would use cane sugar for products in the U.S.

A possible move by Coca-Cola , and other beverage and food industries, to use cane sugar instead of corn syrup as a sweetener would be difficult and expensive to implement, while mostly negative for farmers in the United States.
